E.I L. STEWARD -IGE CREAM MIXER lFiled Aug. 15, 1932 ./'N VEN m R Eow//v ..Snswmo f4@ Patented Aug.` l, 1933 o UNITED STATES www This invention `relatesto vapparatus for mixy insr various kinds and colors of ice cream inl the receptacles in which the vice. cream is shipped so that when thel ice cream isremovedfrom l T75 these receptacles it will have a variegated ap- Y pearance and form .what is now commonly` known as rainbow ice cream.

It is one of the objects of the invention. to provide a comparatively simple apparatus, for

to manufacture andconvenient and eiiicient in operation.

Otherobjects of the invention and the features of novelty will be apparent from the folaccompanying rawing, of which Figure 1 is a side elevation of a machine em bodying my invention, certain parts being shown in section. y I j Fig. k2 is a plan view of the lower part of the machine as seen from the plane 2-2 of Fig.` 1.

Fig. 3 is a plan view of the rotatable vpartition Y member that is employed in the machine.

Fig. 4 is a side elevation vofthe partition member, yand ling the discharge of ice cream from the machine, as the same would be seen from the plane 5 5 of Fig.` 1. Y

Referring to the drawing,v the machine coml prises a skeleton framework which includes four angle-iron uprights 10 which are connected together at the bottom by an angle-iron U-shaped member 11. At their upper ends the uprights or may be made from anglefironor a flat bar, this `ring carrying a rearward `extension or bracket 13 in which a pipe 14 is clamped, the lowerfend of this pipe 14 being seated in a member 15 that is bolted or otherwise secured on the member vl1. Below the ring 12 there is avs'maller ring 16 that is carriedfrom the legs 10 byfmeans of the rods 17. l p

A funnel-shaped hopper 18 is supported in the rings 12 and 16, as shown in Fig. 1, andthe lower end of this hopper carries a casting 19 'in which a slide valve 20 operates to close the lower end of `the `hopper 18.

Arranged within the hopper 18 is a Vmember formed of any suitable number of plates arranged in the form of a star as will be seen from Figs. 3 and 4. These plates are secured together at the center 21 and wire rings 22 and 23 are provided to secure the plates in properly spaced relation. In Figs. 3 and 4 it will be noted the purpose specied, that will be inexpensive lowing descripti n,taken in connection ywith the Fig. 5 is a plan'vew of the valve for control`v v middle 4of the runwayftherel is a platform v,36 Von `which the' receptaclesY 32 are adapted to besepadownwardly projecting 'arm 37 which suitably legs 10 are connected'by a ring-12, which' ringy guided and has it's lower end-pivotally connected a partition that the partition memberfisso formed as tov provide six separate `'compartrnentswithin the hopperv 18, when the `partition".'member is posi-` tioned therein. *Handles` 24 are providedv on the partition .member and project laterally at the top 4of thelhopper as will be seen'from Fig.- 1, Vtheserhandles enabling the operatorl of ythermachine to rotate the `partition member in the hopper for aV purpose to,4 be hereinafter described.

,A tubu1ar' L-shaped 'bracketA .is arranged above the hopper `18 'with a vertical Aleg;` 25 telescoped with the pipe 14 and secured"therein, so;` as to be vertically adjustable, bythe screw 26,1 This bracket `has a horizontal leg 72'7 ywhich projects over thehopper and a cable `28 extendsr through 31 may be'flp'rovidedgfor the cable28 so that it may be freely adjusted` to raisefand lower Athe partition member. `1` L 1 A A runway is provided vatthe bottom ,of the machine for a series of receptacles 32,5to be illled 'o from the hopper 18..r @This runway mayconsist of a pair of `,angle-.irons 33 and guides `34which may` consist of` angle-irons bent `into U "sh'ape'y and having their ends attached to' the legs"l 10 and their intermediate portions supportedefrom the angle-irons`33 Aby' upright bars35.-- "fAt the rately positioned land kraised into engagement with` the casting'is... "ritev platform 36 has a 7 with the lever 38 that is fulcrumedat .39 on a `supporting bracket and has attached to its; o`pi posite end a. treadle member 40. :The ,treadle member 40 has ratchet-'teeth 41 which'cooperate with` the detent 42 so that :when the ktreadle member is depressed by the `iootof the operator t in engagement, with the pedal 43, `the platform 36 will be elevated and the receptacle 32 moved into'` engagement with` the-'casting 19. The en,

42 will hold the ,receptacle inthelelevated posi:

tion until `'che treadle 4memberf is' released from the detent 42. `Springs 44 are provided for yield- 1Q5 -the. partition `V 10o` e' o gagement ofthe ratchetteeth`41 with the detent ing into thereceptacle 32 the operator rotates f i the partition member, by means of the handlesl lpartments formed bythe partition member will be lled by the different kinds or colors of ice cream. One of the receptacles 32, being in position on the platform 36, the treadle member Will` be depressed to bring the receptacle 32 up against the casting 19. The ice creamy should be frozen only to a consistency that Will permitv it to oW freely so that When the valve 20 is opened, the icecream will iloW downwardlyfrom the various compartments in the hopper 18r into the receptacle v32. While the ice creamis ow- 24 and, as a result, the various kinds and colors of ice cream are deposited in the receptacle 32 in spirally arranged layers, so that when it is dipped out of the receptacle in individual portions, each portion Will contain vseveral kinds or colors of ice cream and have a variegated appearance.

l rOn `account of the-diiculty of freezing the difierentice creams to.y the same consistency, it usually happens that with several varieties of ice cream inthe hopperv 18 some `Willflow-'more freely than other Withl the result that, Whenthe valve20 is opened, a slotv-ilowing ice cream inA of the hopperl andthe slow-flowing ice creams Will, as a result, be 'draggedout of their compartments bythe others and the desired mix-v 40` ture Will be jdepositedin the receptacle32, not

withstanding variations in the consistency of dit; ferent ice creams. The ypartition membermay rbe I freely rotated in theelevated position as Welly as when down in the hopper soI that the' differentice creams Willalvvays bek deposited in the receptacle 32`in spirally arranged layers.
